We have a
customer with a twin brewer they have been using for a year—now it is filling less than a pot on a brew
cycle. They want to know why. I told them that I think it may be a lime issue—what do you recommend?

Answer

Linda,A loss in brew volume can occur for many reasons. General maintenance of removing and
cleaning the openings in the spray head(s) daily is a good place to start. The upper mid-West of the United
States is known for hard water (above 6
grains). The minerals dissolved in water precipitate out in the form of calcium and magnesium deposits, when
water in heated to brew temperature. A good place to find out about your water is your local municipal water
provider. Water with a slight hardness(3-6 grains) is recommended for brewing coffee. As a point of
reference 1 grain of hardness is equal to 17.1 mg/Liter or Parts Per Million (ppm).
